Hello, I am Antoon van Hooft a Bachelor applied Physics student. I choose to do my internship at the Fusion group because I find the energy challenges of our future very interesting and I did not have to think twice to take this opportunity to add my contribution on the road to fusion energy. I Focus my project on the optical filters used in an  tokamak plasma diagnostic system. My research consits of determining all the properties of these filters an how they can be used at the KSTAR tokamak experiment in Korea.
